Aluminium et Titane – \u00c0 propos des \u00e9l\u00e9ments<\/h2>\n<\/div><\/div>\n

\n

Aluminium<\/h3>\n

L’aluminium est un m\u00e9tal blanc argent\u00e9, doux, non magn\u00e9tique et ductile du groupe du bore.\u00a0En masse, l’aluminium repr\u00e9sente environ 8 % de la cro\u00fbte terrestre ;\u00a0c’est le troisi\u00e8me \u00e9l\u00e9ment le plus abondant apr\u00e8s l’oxyg\u00e8ne et le silicium et le m\u00e9tal le plus abondant dans la cro\u00fbte, bien qu’il soit moins courant dans le manteau ci-dessous.

Titane<\/h3>\n

Le titane est un m\u00e9tal de transition brillant avec une couleur argent\u00e9e, une faible densit\u00e9 et une r\u00e9sistance \u00e9lev\u00e9e.\u00a0Le titane est r\u00e9sistant \u00e0 la corrosion dans l’eau de mer, l’eau r\u00e9gale et le chlore.\u00a0Le titane peut \u00eatre utilis\u00e9 dans les condenseurs de surface.\u00a0Ces condenseurs utilisent des tubes g\u00e9n\u00e9ralement en acier inoxydable, en alliages de cuivre ou en titane selon plusieurs crit\u00e8res de s\u00e9lection (comme la conductivit\u00e9 thermique ou la r\u00e9sistance \u00e0 la corrosion).\u00a0Les tubes de condenseur en titane sont g\u00e9n\u00e9ralement le meilleur choix technique, mais le titane est un mat\u00e9riau tr\u00e8s co\u00fbteux et l’utilisation de tubes de condenseur en titane est associ\u00e9e \u00e0 des co\u00fbts initiaux tr\u00e8s \u00e9lev\u00e9s.<\/p>\n<\/div>

Aluminium et Titane – Applications<\/h2>\n<\/div><\/div>\n
\n
\n
\n

Aluminium<\/a><\/h3>\n

L’aluminium et ses alliages sont largement utilis\u00e9s dans les applications a\u00e9rospatiales, automobiles, architecturales, lithographiques, d’emballage, \u00e9lectriques et \u00e9lectroniques.\u00a0C’est le principal mat\u00e9riau de construction de l’industrie a\u00e9ronautique tout au long de son histoire.\u00a0Environ 70% des cellules des avions civils commerciaux sont fabriqu\u00e9es \u00e0 partir d’alliages d’aluminium, et sans aluminium, l’aviation civile ne serait pas \u00e9conomiquement viable.\u00a0L’industrie automobile utilise d\u00e9sormais l’aluminium comme pi\u00e8ces moul\u00e9es de moteur, roues, radiateurs et de plus en plus comme pi\u00e8ces de carrosserie.\u00a0L’aluminium 6111 et l’alliage d’aluminium 2008 sont largement utilis\u00e9s pour les panneaux ext\u00e9rieurs de carrosserie automobile.\u00a0Les blocs-cylindres et les carters sont souvent coul\u00e9s en alliages d’aluminium.<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n

Titane<\/a><\/h3>\n

Les deux propri\u00e9t\u00e9s les plus utiles du m\u00e9tal sont la r\u00e9sistance \u00e0 la corrosion et le rapport r\u00e9sistance\/densit\u00e9, le plus \u00e9lev\u00e9 de tous les \u00e9l\u00e9ments m\u00e9talliques.\u00a0La r\u00e9sistance \u00e0 la corrosion des alliages de titane \u00e0 des temp\u00e9ratures normales est exceptionnellement \u00e9lev\u00e9e.\u00a0Ces propri\u00e9t\u00e9s d\u00e9terminent l’application du titane et de ses alliages.\u00a0La premi\u00e8re application de production de titane remonte \u00e0 1952, pour les nacelles et les pare-feu de l’avion de ligne Douglas DC-7.\u00a0Une r\u00e9sistance sp\u00e9cifique \u00e9lev\u00e9e, une bonne r\u00e9sistance \u00e0 la fatigue et une bonne dur\u00e9e de vie au fluage, ainsi qu’une bonne t\u00e9nacit\u00e9 \u00e0 la rupture sont des caract\u00e9ristiques qui font du titane un m\u00e9tal pr\u00e9f\u00e9r\u00e9 pour les applications a\u00e9rospatiales.\u00a0Les applications a\u00e9rospatiales, y compris l’utilisation dans les composants structurels (cellule) et les moteurs \u00e0 r\u00e9action, repr\u00e9sentent toujours la plus grande part de l’utilisation des alliages de titane.\u00a0Sur l’avion supersonique SR-71, le titane a \u00e9t\u00e9 utilis\u00e9 pour 85% de la structure.\u00a0Gr\u00e2ce \u00e0 une tr\u00e8s grande inertie,<\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n
